Even if youíre a great teacher, itís good for the children to hear from others once in a while. Missions conference time at church is a great time, if you can plan ahead, to get very special guests to challenge the children. Ask far ahead of time if one of the missionaries attending the conference can come and speak to the children in your class or club. Let them know a little about the class and help them by giving them a specific purpose you have in mind for inviting them. This could be to challenge the children to become missionaries, witness to their friends, pray or support missionaries or to inform them of what missionaries do or give them a burden for the lost.
